Problems solved by technology

5G (the fifth generation) communication is developed on the basis of 4G communication. It is still in the research stage, and it will take a long time before it is officially put into use.
However, since the signal in the 57-64GHz frequency band has high free-space transmission attenuation and strong atmospheric absorption effect, it is necessary to design a high-gain antenna

Description

technical field [0001] The invention relates to a millimeter-wave patch antenna, in particular to a high-gain T-shaped probe-fed millimeter-wave patch antenna, which belongs to the technical field of wireless mobile communication. Background technique [0002] With the development of mobile communication technology, mankind has entered the era of 4G (the 4th generation) as a whole, and 4G communication has laid a solid foundation for the further development of communication technology. Since the Federal Communications Commission (FCC) of the United States opened the 7GHz frequency band of 57-64GHz as a free frequency band, people have done a lot of work around the 60-GHz frequency band. 5G (the fifth generation) communication is developed on the basis of 4G communication. It is still in the research stage, and it will take a long time before it is officially put into use. Since the signals in the millimeter wave frequency band are very suitable for high-speed data transmiss...
